Description Ranjeeth Rajendran 2014-07-24 15:13:04 UTC
From java we launch LO under Headless mode(socket connection with 5instance of LO) and concurrent request made to convert odt to doc, XOutputStream used to output doc resulted in document mixup.

Concurrent request to convert odt to doc, XOutputStream used to write DOC result in document mixup.

for example-
I have A.odt and B.odt and converting it to A.doc and B.doc respectively.

Either A.doc contains the content of B.odt or B.doc contains the content of A.odt.

This happens very randomly not always.

Steps to reproduce:
1. launch LO under headless mode(5 instance socket connection )from java
2. Make 100 concurrent request to convert documents every document has different contents.
3. Verify the conversion(randomly documents are mixed up)

Work Around:
Dont use XOutputStream wrapper to store file, Save the converted file to local file, and use standard java api to write to the java outputstrem

This issue is reproducible in all versions of LO 3.x and 4.x
Operating System: Windows 7
Version: release

Hi Ranjeeth - 

First: Thanks so much for reporting the issue

Second: Is there any way that you can get us a test kit for this? it's hard for us to reproduce bugs that require us to do something like "100 concurrent requests"

So what would be ideal is if you could provide a zip file with 100 files (simple files if possible) along with a script of some kind to run the 100 concurrent requests.

Lastly, when reporting a bug please always describe each step completely - assume that the bug reader knows nothing about what you're talking about. In this case - "launch LO under headless mode(5 instance socket connection )from java" is pretty advanced - if you could explain this further as to how we can do it, that'd be great.

Apologies for the long delay (we're catching up on a back log of bugs). Marking this as NEEDINFO - if you could provide at least clearer repro steps and if at all possible a test kit, that would be great. Then please mark the bug as UNCONFIRMED. Thanks!
